Title: Printer
Inventor: OTA YUICHI
IPC: G06F3/12
Filed: 1991-07-10
Abstract: PURPOSE:To properly select an operation mode even in the case that a control code does not agree with each operation mode at the time of determining the operation mode by detecting the control code in a printer provided with plural operation modes by selecting the operation mode in which number of the control codes not existing is the smallest in respect of the total number of the control codes. CONSTITUTION:Printing information is received from a host computer 44, and is stored in the printing buffer 43 of a RAM 42. Only the control code is detected, and it is judged whether the control code is the control code of each operation mode 0 or not. When it is judged not to exist in the above operation mode, an error control code counter 0 is increased by '1'. The above processing is executed repeatedly, and the printing operation mode is determined on the basis of the counter whose number of error control codes is the smallest among the error control code counters 54.

Title: Optical amplifier
Inventor: NISHI NORIO
IPC: G02F1/09
Filed: 1989-07-28
Abstract: PURPOSE:To easily eliminate polarization dependency by setting the direction of polarized light wherein the maximum gain of a 1st and a 2nd semiconductor laser is obtained to the direction of polarized light that light beams projected from a 3rd a 4th optical waveguide given after passing through Faraday rotators. CONSTITUTION:A semiconductor laser 8-1 is rotated around the optical axis by 45 deg. and arranged so that the active layer of the semiconductor laser 8-1 coincides with the electric field direction of TE polarized light projected from the 3rd optical waveguide 3-3 since the electric field direction rotates by 45 deg. after passing through the Faraday rotator 6-1. A semiconductor laser 8-2 is rotated around the optical axis by -45 deg. and arranged so that the active layer of the semiconductor laser coincides with the electric field direction of TM polarized light projected from the 4th optical waveguide 3-4 since the electric field direction rotates by 45 deg. after passing through a Faraday rotator 6-2. Thus, input light is split into two specific polarized light beams, whose polarization directions are made coincident with the direction of the polarization where the maximum gain of the semiconductor lasers is obtained through the Faraday rotator 6-2 to easily eliminate the polarization dependency.

Title: Fault detecting device for vehicle
Inventor: TAKAHASHI HIROSHI
IPC: G06T7/00
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To quickly detect an obstacle that suddenly appears. SOLUTION: A CCD camera picks up the image ahead of a vehicle, and imaged video is subjected to differential processing to prepare an image obtained by enhancing horizontal and vertical contours. The image is subjected to discrete cosine transformation, to calculate an information distribution in a frequency space. Information change in the image is detected from the arrangement of DCT coefficients showing the information distribution in the frequency space. That is, when a vehicle and a person appear suddenly in the image, the value of the DCT coefficient at a prescribed position increases in response to the vehicle and the person. Then, when the value of the DCT coefficient at the prescribed position increases equally to or more than a set value, it is possible to detect that a vehicle and a person corresponding to the position appear.  For instance, when the 16-th, 26-th and 29-th coefficients in which only a horizontal frequency is high are increased, it can be detected that a vehicle appeared in an image pickup space.

Title: Distortion generating circuit
Inventor: HAMADA AKIRA
IPC: H03F1/32
Filed: 1988-08-05
Abstract: PURPOSE:To compensate up to the 5th order distortion in a power amplifier or the like by devising the circuit in which the quantity of the 3rd order distortion and the 5th order distortion with respect to an input signal is set optionally. CONSTITUTION:The level and phase of a 5th order distortion generated in a 3rd order/5th order distortion generator 5 are adjusted to a desired value in a synthesizer 8 synthesizing two distortion inputs via variable attenuators 6, 7 and variable attenuators 3, 4 are adjusted to vary the level and phase of the synthesized 3rd order distortion component from a 3rd order distortion generator 3 and the 3rd order/5th order distortion generator 6 freely and the resulting output is given from an output terminal 52. However, the level and phase of the 5th order distortion component set initially are unchanged. Thus, it is possible to provide an optional level and phase to each of the 5th order distortion component and the 3rd order distortion component respectively. Thus, the distortion compensation circuit up to the 5th order distortion not only the 3rd order distortion only is easily formed.

Title: Pole plate
Inventor: NAKAYAMA TAKASHI
IPC: B23Q3/154
Filed: 1984-09-21
Abstract: PURPOSE:To secure a pole plate capable of maintaining a high degree of flatness, by embedding a core material, which has a expansion coefficient smaller than the coefficient of thermal expansion and an elastic modulus larger than the modulus of longitudinal elasticity, in a charging resin member of a split groove. CONSTITUTION:A core material 28 has a smaller thermal expansion coefficient than that is a nonmagnetic resin member 26 so that it shows a smaller expansion value than that of the member 26 due to a temperature rise. And, since it has a larger modules of longitudinal elasticity than that of the member 26, it is in no case expanded longer by thermal expansion of the member 26. Wherefore, the core material being embedded inside the member 26 mainly checks expansion of the member 26 in a depth direction of a groove 24, that is, in a plate thickness direction of a metallic plate 22 by action of a warp 28a, and also checks protrusion of the member 26 from a top surface of the metallic plate 22. Therefore, the member 26 will not protrude over so largely as in the past despite a temperature rise, whereby jogs on the top surface are restrained from occurring. Thus as a source of magnetic force, it is usable for a face plate of a magnetic chuck provided with a permanent magnet built-up body.
